Have you ever tried to make your own custom color of crayon by melting several together? These blanks are what they would look like – beautiful colors swirled together creating random, unique patterns. Made from an opaque resin that is non-brittle, the blanks are easy to drill and turn and require no topcoat finish. Simply drill, turn, sand, and polish to a high gloss shine. Proudly made in the USA, blanks measure 3/4" x 3/4" x 5".
